I've read that steroids that shutdown test without mimicking it can cause lethargy, while some steroids show test-like effects... usually ones that aromatize, they will increase sense of well being and libido and should improve lethargy.
Unfortunately, I've also read enough to see that some people who run ph X will get lethargy and lost libido and some people get a sense of well being and increased libido. Take Epi and Phera for example, heard a lot of conflicting information about these.
Really the only way is to try them and find out, but i think the "wet" ones like Phera and Dbol are supposed to be better for energy.
1T is known for causing lethargy tho so I'm sure whatever else you try won't be so bad.
